发明名称 Method and device for locating moving objects
摘要 In order to provide a method for locating moving objects that will allow high precision in position determination and thus largely eliminate sorting errors, and also to provide a device suitable for executing the method, it is envisaged that on at least one defined location within the reading range of an interrogator (16) arranged in a stationary position, an interference pulse, which influences a response signal transmitted by a transponder (20) carried by a moving object (12) in response to a signal transmitted by the interrogator (16), is exerted on the object (12), and a position of the object (12) is determined in dependence on a time when the influence of the response signal occurred.
